In those who go on from good to better, the good Angel touches such soul sweetly, lightly and gently, like a drop of water which enters into a sponge; and the evil touches it sharply and with noise and disquiet, as when the drop of water falls on the stone.
And the above-said spirits touch in a contrary way those who go on from bad to worse.
The reason of this is that the disposition of the soul is contrary or like to the said Angels.
Because, when it is contrary, they enter perceptibly with clatter and noise;
and when it is like, they enter with silence as into their own home, through the open door.
